The Powerslide Spinner Wheels at 84mm and 90mm are perfect for high speed urban freeskating and fitness skating activities. These sizes come in a race profile (footprint) for added speed, but still offer great control, stability, and even the ability to perform controlled slides! 
 
All Spinner Wheels are 88A in hardness (some 84mm had a misprint stating 85A but this was corrected on later production). The cores are strong and durable to better withstand the pressures of those that skate off curbs, stairs, and the like. Reinforced 5-Spoke Turbine Core combined with the same special urethane used on the other sizes.
